To all whom it may concern:

Be it known that I, RoLANn citizen of the United States, residing at Los Angeles', of California, have invented a new and useful Gas-Generating Oil-Burner, of which the following is a specification.

The main object of the present invention is to provide a burner in which the oil isconverted into gas by the action of a current of air passing over the oil and inducedby a direct draft. I

A further object of the invention is to provide a device for this purpose of extremely simple and cheap construction.

Another object of the invention is, to pro vide a burner which can be readily cleaned.

Another object of the invention is to provide the burner with means for preventing dangerous accumulation or overflow of'oil, in case the oil is turned on when not lighted or is being supplied faster than it is con sumed. I J

In the accompanying drawings illustrating the invention: Figure 1 is a perspective of the burner. Fig. 2 is a vertical section thereof. Fig. 3 is a horizontal section on line afi-w in Fig. 2. Fig. 4t is a side elevation of the burner, showing the application c'of'a deflecting cap plate therefor. 7 The base a fire pot, is formed with an 'oil cup 2, and with concentricannular airdeflecting flanges 3, 4.

011 cup 2 is formed as a tubular enlargementor head on astandard 5, rising from base 1, said standard being tubular and connecting with an oil supply pipe 6 which screws into base 1 at the bottom of the standard. Said head is formed with a corn" cavity or depression in its top, to serve as the oil cup and with a-raised' rim 2, said concavity being shallow and Wide to provide largeevaporating surface. The annular space 7 between flanges 3 and 4 extends to the space beneath base 1, so as to communicate therewith, and is openat the top, webs or bridges 9 extending across this s ace to connect the central and outer base. The inner flange 3 is 0 same diameter as the 011 cup 2 and the chamber or cup within this flange 3 serves as a receptacle for overflow oil, a drain pipe 8 being provided therefor. The outer flange 4 extends up to about the level of the top of in the county of Los Angeles, State 1 which is adapted to fit within arts 0 the 1 about the the oil cup and a deflector ring 10 rests on 0-CASAD, a

top of flan e 4, and extends toward the lip or rim of t e oil cup, the inner edge of the rim being slightly above the rim of the oil,

cup, to form an annular air admission slot 11. Said ring 10, has an annular flange or head 12 to fit the flange4 and hold the ring in proper-position.

The operation is as follows: is turned into; cup 2 and is ignited. After natural draft has been started, air is continually drawn throughpassalg 7 and through slot 11, said alr ssumg in a sheet or nearly hori- "zontal jet directly over, the surface of the oil in. the oil cup, thereby causing evaporation of theoll, and simultaneously causing Patented'sept. 10,1912.

the vapor of the oil to be mixed with the air,

forming a mixture which burns without smoke and produces a flame which is blue or white according to the amount 'of oil sup plied. The air, in passing up through --the passage 7 is heated by the walls ofsaid passage, thereby expediting the evaporation,

and producing, more perfect combustion. It will be noted that the'air passage 7 is direct, from the space below the base to the 'air outlet 11, thus obtaining the maximum velocity of the air jet. The head 2 formed on top of the tubular member 5 extending upwardly from the plate 1 extends outwardly from said membere to substantially the same di-' ameter as the flange 3, so that any solid ma= 'terial which c'olleetsxin the oil cup 2 in said head can? be scraped-therefrom and passing through the annular slot llwill fall into-the space 7 outside ofvthe flange .3, and will be discharged ,thrbugh thejopeningin the plate 1. The oil cup? being opened or exposed at the top and the deflecting ring extending only far. enough to deflect the alr over the cup without ex ending over the cleaning by scraping as above stated. The

peripheral face of the head 2 is rounded on its lower corner as shown, so that any oil- .escaping over-the said peripheral face by itself, the cup is completely exposed for standard 5 are preferably cast in' one piece, so that there are only two pieces in the burner, namely, this casing and the ring 10.

If desired a deflecting cap plate may be provided a's'indicated at 15 in Fig. 4, said cap plate being of any suitable form and having legsor lugs 16 to rest on the deflecting ring 10, the function of said cap plate being to deflect the flame laterally and prevent too great concentration of heat at'the point directly above the center of the burner.

What I claim is 1. A gas generating oil burner comprising a base provided with inner and outer flanges extending upwardly therefrom to form -=an air passage extending to the bottom of the base and open at its lower end, an oil cup extendingwithin the outer flange and over the inner flange and provided with an oil supply connectiomsaid oil cup having a raised rim, and a deflector-ring extending inwardly from the outer flange into proxiinity to'the oil cup, forming an air inlet directly over the rim of the oil cup to project a sheet of air over the oil in the cup.

2..A gas generating oil burner comprising a base, provided with inner and outer flanges extending upwardl' therefrom to form an air passage exten ing to the bottom of the base and open at its lower end, an oilcup extending over the inner flange and withinthe outer flange and having a raised rim, oil supply means for said oil cup, and a deflector-ring extending from the outer flange into-proxlmity to the rim of the oil cup, formin an air inlet directly over the rim of the 011 cup, to project a sheet of air directly over the oil in the cup. 3. A gas generating oil burner comprising a. base, provided with inner and outer flanges extending upwardly therefrom to form an air passage extending to the bottom of the base and open at its-lower end, an oil cup having a lower rounded corner extending over the inner flange and within the outer flange and having a raised rim,

oil supply means for said oil cup, a deflector extending from the'outer flange into proximity'to the rim of the oil cup, forming an air inlet directly over the rim of the oil cup,

- to project a sheet of air directly over the oil supply means for said oil cup, a deflector extending from the outer flange into proximity to the rim of the oil cup, forming an air inlet directly over the rim of the oil cup, to. project a sheet of air directly over the oil in the cup,-and a drain connection communicating with the space :within the inner flange, said deflector being removably supported in the outer flange.

5. A gas generating oil burner comprising a base provided with inner and outer flanges extending upwardly therefrom to form an air passage extending to the bottom of the base and open at its lower end, an oil cup having a lower rounded corner extending within the outer flange and over the inner flange and provided with an oil supply connection, said oil cup having a raised rim, a deflector-ring extending from the outer flange int-o proximity to the oil cup, forming an air inletdirectly over the rim of the oil cup to project a sheet of air over the oil in the cup, and a deflecting cap plate extending above the oil cup and 'ir deflector-ring and separated therefrom for the purpose set forth. i

In testimon whereof, I have hereunto set my hand at JOS Angeles, California, this 3rd day of July, 1909.
